MudI-Guardsfor Cycles, Motor-Cycles, and

Vehicles; and I do hereby declare the.- fol.- lowing to be a full,clear, and exact de scription of the same.

relating tomudguards for cycles, cles and vehicles.

Inaccordance with. my invention I provide auxiliary guardsor-shields intheform motor cyof strips for protecting the spaces at the:

sides of the wheel either inside or outside the usual stays, whichsupportthe, ordinary guards and these strips or guards are disposed in aplaneat right angles to that of thewheel. and more or less radial inrespect tothe wheel.- and are pivotally. mounted upon stays so as to becapable of being turned into or out of operative position as desired.The strips may. be mounted. on the usual stays or on. additional staysand attached to the forks, carrier struts or other convenient parts solong as they are pivotal on such stays.

It has been before proposed to arrange a trough mudguard in twocircumferential sections fastened. to a rigid stay piece, the

sections being parallel. to. the plane of the wheel. and capable ofhinging upon the stays so asto open away from the wheel to per.- mittheir inner surfaces to be. cleaned. My invention is distinct from suchan arrangement as my auxiliary guards are so pivoted that they may beturned into or out. of operative position without undoing any fasteningdevice and without any detachment or partial. detachment. Further ithasbeen proposed tousean auxiliary mudguard disposed in. a plane atright. anglesto. that of the wheel and mounted upon, one ot the stays ofthe ordinary mudguard but such mudguard. was fixed: and. not pivotal.

Referring to the, drawings :.-Figure l. is a: perspective view with the.auxiliary strips in; position. Fig. 2.v is a. front end view of myprotecting strips, or guards detached from the stays but. represented intheposition they occupy whenin use. Fig.

Fig. 6. isa. perspective view; of a. motor cyclemudguard with adjustable auxiliary guards on the stays ofi the troutextension. Fig... 7. shows a: further modification. Fig. 8. is a.detailfof a modification.

In. the example. illustrated by Figs. 1, 2 and; 3- I mount a guard A oneach stay 6% of, the ordinary mudguard Each of This invention comprisesimprovements tiona On each side ofxtheportion al the material maybeturned. over to form spring clips at, or suchohps arecsecured. at,such parts. to embrace a. stay or. stays in. amannor allowing the guardto be turned, or

pivoted. upon. the stayso that. it may. be

turned into a position for use, and. out of same when desired;Theportion a? is pref.- erably cutso that itsedgea?v is. inclined tofollow approximately thev plane. the, spokes of the wheel occupyinrotationythiswill. be clearlyseen. in Fig. 3. The portion. a? isfurther. arranged in relation to. the mounting and. to the outwardlyprojecting part. a5

. so: that when imposition on thestay and. the part a? is, against. the.ordinary mudguard a space is left. at. the side of a toclear'the rimand. tire.

The example here shown. presents the, in.- wardly projecting portion awhich. protects the space. between the. stays and, the. rim. of

the Wheel, and. also the. outwardly projecting portion at. Theseportionsare arranged substantially; at right angle to the vertical planein ,whichthe wheel rotates and may be either .oirthe lower stays-16 asshown-.or on staysfrom apfrontextension of the. ordinary guard.

I need notemploy both theparts at and. a. but may use one sideprojection. only if desired. so, long as, the, guardsv are pivotallymounted upon thestay. or stays.

I. haveyhere shownfi the. guards. with. the

rear of] the portion. a extended. and bent down as. at a? which. formguardsrprojecting on each. side, of thewmudguard. Thesepontionsat may hecontinued. down, to present a. considerable extension to. the: mudguardproper. l

Whenthe guards A are of metal or cellu.- loid. they can eachbeconveniently, formed in one piece with the spring clips a or the lattermay be attached as desired. The guards are very simple in attachmentsimply requiring the clips a to be sprung on to the stay and the guardsmay be turned into desired position. When mounted in this way they maybe turned on the stay so as to be adapted for placing in the positionshown for use or for turning. at right angles to that position when outof use; the grip of the parts a upon the stays retaining the guards indesired position.

When the guards are mounted on the stays of a front extension thisturning is of particular value as it enables the guards to be turned.out of the wind when not required to arrest mud splashing.

The guard illustrated by Fig. 4 is similar to those in Figs. 1, 2 and 3,as regards having both portions a and a, thelatter portion of each,however, may be inclined at the edges toward the rear to give a widerprotection there. The portion a on each guard is provided with tongues awhich bear against the edge of the ordinary mudguard B to maintain theguards A against accidental turning on the stay. When it is desired toturn the guards these portions a are first disengaged.

v By Fig. 5 I have shown my pivotal guards attached to a movable stay sothat they may be raised and lowered. The stay 5 may be in one piece orthe two sides are connected at the back 5 and receive a pin or stud bwhich works in a slot 5* or a series of holes in the mudguard and underthe binding action of a suitable nut the stay is secured in desiredposition. I may use a washer plate preferably inside the guards of asize suflicient to cover the slot or I may use a sliding extension ofthe guard.

By. Fig. 6 I have shown my pivotal auxiliary guards A clipped or clampedon to an adjustable stay 5 attached to the front extension of a mudguardin which a slot 5 is formed. The guards prevent mud being carried up atthe side of the front wheel and being blown back on to the rider andwhen. the stay is moved toward the forks of the; machine the guardsprevent rain beating on the knees of the rider. The auxiliary guards.may be carried up above the ordinary guard if desired so long as theyare pivotal upon the stay.

Fig. 7 shows a further modification in which the guards are carriedacross the sides of the wheel; the pivotal side guards A are mounted ona stiff strut or stay 12 and are provided with hinged extensions at thetop as at a which may form knee protectors and may be readily turneddown out of use. The guards preferably have a supporting frame a andthis is jointed at a with a joint having suitable bindingor clampingmeans for setting the joint in desired position. Instead of being hingedthe extensions may be detachable and may be secured in any convenientmanner such as by screwing into an anchored nut a as in Fig. 8

.or the ends of the frame of the extension may be simply pushed into thetubular stays of the lower part and form a tight fit in same.

The guards A are arranged for turning on the stay 5 when the clips orclamps are released so that after turning down the parts a" the wholeguard may be turned back fiat against the side of the forks or sideguards.

In any of the examples set forth I may form the side margins of thestrips of auxiliary guards with bent down portions for stopping the mudsplashing outwardly at the sides. The arrangement of the auxiliaryguards as pivotal structures is of considerable advantage when a machineis placed against the wall, or structure at the side of the wheel, orwhen stored and on numbers of other occasions; also during riding theguards can be turned edgewise so that no side projections of any kindare left.

What I claim then is 1. An auxiliary mudguard for cycles, motor cyclesand other vehicles, mounted upon stays, and having means whereby it maybe retained parallel to the plane of the wheel or at right anglesthereto; substantially as set forth.

2. In a mudguard for cycles, motor cycles, and other vehicles, thecombination of a stay, an auxiliary mudguard pivotally mounted uponsame, and means whereby the said auxiliary mudguard may be retained in aposition at right angles to the plane of the wheel or parallel thereto;substantially as set forth.

3. In a mudguard for cycles, motor cycles, and other vehicles, thecombination of a pair of stays substantially radial in respect to thewheel and one on each side of said wheel, auxiliary mudguards pivotallymounted upon same, and means whereby the said auxiliary mudguards may beretained in a position at right angles to the plane of the wheel orparallel thereto; substantially as set forth.

4. In a mudguard for cycles, motor cycles, and other vehicles, thecombination of a pair of stays substantially radial in respect to thewheel and one on each side of said wheel, a pair of auxiliary mudguards,spring clips for pivotally mounting said auxiliary mudguards upon saidstays, so arranged that the auxiliary mudguards may be turned to andretained in a position at right angles to the plane of the wheel orparallel thereto; substantially as set forth.

5. In a mudguard for cycles, motor cycles, and other vehicles, thecombination of a pair of stays substantially radial in respect to thewheel, and one on each side of said Wheel, a pair of auxiliarymudguards, spring clips formed by bending over the edges of the mudguardand embracing said stays, so arranged that the auxiliary mudguards maybe turned to and retained in a position at right angles to the plane ofthe Wheel or parallel thereto; substantially as set forth.

6. In a mudguard for cycles, motor cycles, and other vehicles, thecombination of a Wheel, a mudguard partly surrounding the Wheel andconcentric therewith, a palr of stays mounting said mudguard upon thehub of the Wheel, and a pair of auxiliary mudguards pivotally mountedupon said stays, so arranged that the auxiliary mudguards 15 may beturned to and retained in a position at right angles to the plane of theWheel or parallel thereto; substantially as set forth.

In testimony whereof, I have signed my name to this specification in thepresence of 20 two subscribing witnesses.
